With 235 marks in your PCM board exams and 50 marks in KCET, your rank could likely fall around 60,000 to 80,000, although this is an estimate and may vary depending on overall competition and exam difficulty. Your overall percentage would be around 47% in KCET if we consider your score out of 100. However, the exact rank and percentage also depend on how other candidates performed this year, so final results may differ.
